Abstract: An ultrasonic anti-theft device is constituted by a transducer-emitter with its excitation circuit, provided in order to establish a substantially stationary acoustic field inside the vehicle. The transducer-receiver is equipped with its receiver circuit. It is followed by a variable-gain amplifier (22), then by a rectifier (23), with, in parallel with these, a servocontrol loop (24,25) for the gain of the amplifier (22), this loop being of a supercritical characteristic. The output voltage from the rectifier (23) can then be the subject of detection by variation (26), then of shaping by a pulse generator (27). The pulse signal available next makes it possible to establish the alarm by a simple counting of pulses. <IMAGE>

Title: Fixation system for tubular bone fractures.
Inventor: BAUMGART RAINER
IPC: A61B17/68
Filed: 1990-04-18
Abstract: A fixation system for tubular bone fractures (3, 4) consists of an elongated, flattened fixation element (20) and bone screws (10) connected to each other by means of a screw (11), a cone (16) and a conical segment section (15). The fixation element (20) has an essentially rectangular cross-section and is made of tissue-compatible, high-strength material, in particular implant steel. At least two holes in each of the two end sections (21) of the fixation element (20) extend through its opposing wide faces. The bone screws (10) are inserted through these holes. The fixation element (20) is made in one piece from the two relatively rigid end sections (21) and an intermediate connecting section between them, or from two superimposed parts connected to each other in the end sections. The connecting section (31) is elastic in comparison with the end sections (21), because its cross-section is smaller than that of the end sections (21). This compact fixation device can be implanted under the skin and eliminates transverse forces as well as flexing and torsional moments in the region of the fracture, without the implantation affecting the circulation. In addition, the normal forces in the fracture region can be adjusted as required.

Title: Apparatus and method for conjoint adjustment of both the inner and outer grinding spaces of a pulp defibrating apparatus.
Inventor: REINHALL ROLF B
IPC: B01F23/57
Filed: 1990-10-16
Abstract: A method and apparatus is provided for conjoint or simultaneous adjustment of the gap spaces of the inner and outer grinding zones of a pulp refiner apparatus in a single step. The inner grinding zone is generally radially oriented, and merges into an outer inclined grinding zone. Pulp stock to be ground is introduced into a central inlet position and is accelerated through the inner and outer grinding zones by centrifugal forces generated by a pair of grinding members which rotate relative to one and other. The opposed surfaces of the relatively rotating members each carry a plurality of concentric rows of teeth, and the gap spacing of the inner grinding zone is defined between adjacent surfaces of the teeth. The adjacent teeth defining the inner grinding zone are arranged so that adjustment of the gap space of the outer grinding zone simultaneously controls the gap spacing of the inner grinding zone without the need for separate adjustment. Retarding rings are provided adjacent to the concentric rows of teeth to prevent pulp from by-passing the grinding spaces between adjacent teeth.

Abstract: A bar code reader (10) includes a first (32) and second (42) memory arrangement in which a two dimensional image containing the image of a bar code symbol at a random location and orientation is stored in a first memory (32). Thereafter, the contents of the first memory (32) is processed by a specialized controller (34) to determine whether any portion of the stored image is likely to contain a bar code symbol, and if so, at what location. If a bar code symbol is located, then the portion of the image stored in the first memory (32) which has been identified as likely to contain a bar code symbol is transferred to the second memory (42). In the second memory (42), the stored image is processed by a digital signal processor (38) in order to orient, filter and scan the stored bar code image. The dual processor (34, 38), dual memory (32, 42) arrangement permits the performance and cost of an omnidirectional bar code reader to be optimized by chosing the memory type and the particular processor most suitable to the processing algorithm for each of the bar code image processing tasks.

Abstract: A mechanically pressurized electronic fuel injector (5) is for use in internal combustion engines and is actuated by the engine valve train. The fuel injector (5) has an injection stroke for discharging fuel into the engine and a metering stroke for receiving a predetermined volume of fuel in the injector (5). During the injection stroke, a coupling member (20) contacts a timing plunger (16) and transmits a compressive force from the engine valve train. The coupling member (20) and the timing plunger (16) are not mechanically connected together and are capable of independent relative movement. During the metering stroke of the injector (5), the timing plunger (16) is returned to its pre-injection position under the pressure generated by the fuel entering the timing and metering plunger chambers (26 and 33).

Abstract: In the method for bending metal sheets (4), the metal sheet (4) to be bent is slid through a guiding arrangement (5, 7) and thrust against a deflection member (9), a force acting counter to this bending force being exerted on the metal sheet (4) ahead of the deflection member (9). The bending apparatus has a deflection member (9) and a thrust device (3) which thrusts the metal sheet (4) to be bent against the deflection member (9). Arranged ahead of the deflection member (9) is a guiding arrangement (5, 7) for guiding and providing a counter-abutment for the sliding metal sheet (4) as it is thrust forward. A bar (9) which can be adjusted vertically (13a), horizontally (13b) and in its inclination (13c) to the feed direction (16) and has an inclined deflection surface (11) is used as the deflection member. A horizontally and vertically adjustable roller can also be used instead of the bar (9). Corrugated sheets can be produced by the alternate use of one deflection member arranged on each of the two sides of the sheet. The method according to the invention can be used to produce good quality tubes and gutters, even those with a small bending radius, in a simple manner. The tube bending device according to the invention is simple in construction, is simple to adjust and allows relatively long tubes with a small diameter to be bent. <IMAGE>
